Description

Full text follows: The building materials are the major contributors of indoor radon/thoron after soil. The health risks incurred merely by breathing the air at home can substantially exceed the general limits on risk that regulatory agencies impose in controlling pollutants in indoor environment. Radon/thoron concentrations in the model room have been predicted based on the exhalation rates from wall, floor and roof. The samples were analyzed using smart Rnduo under standard protocols developed by BARC Mumbai. Calculations for model room that indoor concentrations of radon/thoron shows significant variation depending upon the types of building material used. This variation of indoor radon/thoron concentration is because of the different diffusion lengths of these gases in different materials and the concentration of uranium/thorium present. The theoretical prediction have been validated by experimental measurement of indoor concentration of radon/thoron using passive detectors.
